WILLIAM JACKSON, 0F JACKSON, MICHIGAN.

To all wlwmz't mag/concern.'

Be it known that I, WILLTAM' H'. JAcK- soN, a citizen o'f the United States, residing vat Jackson, inthe county of Jacksonand `State ofv Michigan, have invented certain new and useful' Improvements .in Grasolene- Valve Locks, of Which'the following is a. specification.

rIlle object of this invention is to provide a novel construction of key-controlled lock for turning plug valves whereby the valve canbe openedv only by a key designed for the particular lock'which is connected therewith.

In the accompanying drawings showing referred form of the inventionigure 1 is a view, in perspective, of the valve as embodied in the fuel supply line. Fig. 2 is a vertical longitudinal section, Figs. 3, 4, 6, 7, 8 and 9 represent different forms of key-receiving disks or heads for the turmng plug, and

5is a plan view of the key-receiving facing disk embodied in the device shown in Fig. ll, and adapted to receive the key therein shown.

In detail, the invention comprises a valve body 1 having a longitudinal fuel passage 2 therethrough to each end of which is connected the respective terminals of 'a fuel supply line as indicated at 3 and 4, said terminals being secured in place b suitable unions 6 and 7 respectively.. he valve body l isprovided with. a vertically extending shut-off element hole 8 which is at right angles to the axis of the fuel supply line. Integral with the valve body 1 is a vertical iange 9,whichisl recessed, as shown at 10, to

accommodate the enlarged upper end 11 of a. shut-olf element 12 whichis in the form of a turning plu having a passage 13 which will register wit the passage 2in the valve body when the turning plugis moved to the proper position.. The turning plug 12 has, at its lower end, a threaded tip 14 which receives a washer 15 and a nut 16 which hold the said turning plug inv placel within the valve body 1. A. dependent vertical flange 17 .is provided on the bottom ofthe valve body 1 surrounding thethreaded end 14 and is, itself, threaded as shown at 18 to receive a ca nut 19.

' T e upper end of the turning plug 12 is, as reviously stated, seated in the recess 10 witliin the vertical iange 9 and is/tapered spwincanonpf :letters Patent. Patented Jan, 25, 1921. 4.Application Ied January 12, 1920. Serial No. 350,753. i

vided with a slot 29, which slot is elongated l in the major portion of the disk as shown at 30 to permit the insertion of a key 31l when said slot29 registers with the diametrically opposite slots 26. This disk 27 is supported on a sleeve 32 positioned concentrically Within the tubular member 23 and' against the lower end of` which rests a second keyreceiving disk 33 having a suitable aperture 34 which, when registering with the slot in the upper disk 27 will permit the insertion of the key so that the tongues 35 thereof may be engagedwith the holes 21 in the top offthe turning plug to permit the turning plug t0 b'e moved to the open or closed position by turnin the key. The lower disk is other means 37 extending through the tubular member 23 and into the said liange 9 so as to prevent removal of the lock from the valve. A cover or cap 'member 38 is removabl fitted over .the entire locking structure an carries an eye 39 connecting with a chain 40 which secures the dust cover o r cap to a lug 41 on the valve body 1. In Figs. 1 and 2 the type of disk shown for recelving the key is merely one example of what may be used but it is obvious that any desired number of disks or hole locations in the disks may bev resorted to and for this vpurpose thereis illustrated in Figs. 3 to 9 1n- Psi elusive various forms of disks requiring different keys. In all of the figures it is to be diate disks as no proper impression can be made for a key nor can wires or other forms of implements be made to open the valve.

`The facing disk 24 may be threaded into the outer end of the support 23 or may be formed integral with the saine. If the disk be formed integral with the support, the disks 33and 27 with the spacing sleeve and ring will be inserted into the tubular support through the open en d' of the same before the support is placed in position upc-n the valve body and all these assembled parts then placed upon the valve body and secured in the manner described. If the facinof disk be provided With screwthreads to engage corresponding threads in the'outer end of the tubular support, the spacing ring and sleeve and the key-receiving disks 27 and 33 will be inserted through the outer end of the tubular support after the same has been secured in position upon the valve body and after all the'parts have been placed within the tubular support the facing disk will be screwed outer end of the tubular support, and a key receiving disk mounted in said support in juxtaposition to the facing disk for free turning movement but held against endwise movement, the key-receiving disks being in spaced relation longitudinally of the tubular support and the facing disk and the key-receiving disks being constructed to per- Init engagement of a key in the turning element in one position and prevent such engagement in all other positions.

2. The combination with a body, and a turning element mounted therein, of keyreceiving means on the end of said turning element and turnable therewith, a tubular support on the body axially alined with the turning element, a spacing ring disposed within said support and bearing on the body around the key-receiving means on the end of the turning element, a key-receiving disk fitted within the tubular support for turning movement and held against movement toward the turningwelement by said ring, a spacing sleeve fitted within the tubular support a ainst the outer face of said keyreceiving isk and holding said disk against outward movement, a facing disk in the end of the tubular support, and a key-receiving disk fitted in the tubular support for turning movement and held against end- 'wise movement by the spacing sleeve and the facing disk, the facing disk and said key-receiving disk being constructed to permit the insertion of a key in one position and prevent the insertion of a key in all other positions.
